Actually I think I am going to go back to using the Android version.
I started using libreelec because the 17 versions of KODI all had problems displaying smooth videos on my Tronsmart MXIII-PLUS boxes.
I had found out that this was because the hacked up Tronsmart mediacodec really did not handle resolution changing, very gracefully at all.
However, KODI 18.1 on my Tronsmart MXIII-PLUS Android 5.1.1 boxes, seem to be perfectly smooth right out of the box, no tweaking needed.
